GUI Fitting Issue with 1920x360 Resolution on HDMI Display - i.MX8MP

Hello NXP Community,

I'm working with an i.MX8MP processor and a 1920x360 HDMI display. While the resolution displays correctly at 60Hz, I'm encountering an issue where the GUI doesn't fit properly within the display area.

Here are the values I am using in my EDID configuration:

#define CLOCK 60000 /* kHz */
#define XPIX 1920
#define YPIX 360
#define XY_RATIO XY_RATIO_16_9 // Tried with XY_RATIO_16_3 as well, but no improvement
#define XBLANK 280
#define YBLANK 45
#define XOFFSET 88
#define XPULSE 44
#define YOFFSET 9
#define YPULSE 5
#define DPI 96
#define VFREQ 60 /* Hz */
#define TIMING_NAME "Linux FHD"
#define HSYNC_POL 1
#define VSYNC_POL 1

The resolution itself (1920x360) displays correctly, but the GUI content extends beyond the visible screen area vertically. I’ve tried adjusting XY_RATIO between 16:9 and 16:3 with no success. Additionally, I’ve experimented with increasing YBLANK and YOFFSET values, but the GUI still does not fit as expected.

Are there specific values I should prioritize adjusting (e.g., YBLANK, YOFFSET, or sync pulse settings) to achieve a proper vertical fit ?if yes ,What value ?
Is there any other area in the device tree or EDID settings I should verify or modify to resolve this vertical fit issue?

Any guidance on specific adjustments or other configurations to check would be much appreciated!

Regards,
Dheeraj

Hello,

You have to modify the LCD driver since your resolution is not supported by default.
